Procjena botaničkog sastava pašnjaka na različitim područjima s posebnim osvrtom na udjele terpena, koji osim učinka na terpenski profil arome mesa preživača mogu imati i potencijalni imunomodulacijski učinak, od bitnog je interesa suvremenog ovčarstva u R. Hrvatskoj. U istraživanjima u okviru ovog rada, pokazano je da ljekovite svojte bogate terpenima poput gospine trave (Hypericum perforatum L.), stolisnika (Achillea millefolium L.) i matičnjaka (Melissa officinalis L.) zbog statistički značajno veće učestalosti, gustoće i pokrovnosti na pašnjacima Velike Crkvine, u odnosu na pašnjake u Kvarte, potencijalno utječu na bolji imunosni status ovaca. Stoga su u ovom radu dobiveni rezultati znanstvena preporuka za daljnju procjenu biljnog sastava pašnjaka u Velikoj Crkvini tijekom istraživanja HRZZ projekta IP-2016-06-3685 u cilju postizanja dodatnih saznanja o učinku terpena na zdravlje i aroma sastav janjećeg mesa i to sve u svrhu proizvodnje inovativnih funkcionalnih proizvoda od janjećeg mesa.

Drawing upon Fischbein's theory of figural concepts, the starting point of the paper is the use and value of the history of geometry in mathematics education - first point that we make historical reference are theorems of Eudemus of Rhodes and Thales of Miletus and the second one is elaboration of these theorems in work of Serbian mathematicians Mihailo Petrovic Alas. Fischbein's theory is mainly based on a hypothesis that geometry deals with mental entities, the so-called geometric figures, which simultaneously possess conceptual and figural properties. Fischbein called the geometric figures figural concepts because of their nature. We have analyzed the internal tensions of the concepts of angle and cube, which may appear in figural concepts because of their double nature, developmental aspects and didactical implications. The goal of the research was to examine the pre-service primary school teachers' geometric reasoning regarding the correlation between figural (pictoral) and conceptual properties of geometric objects (angle and cube) in order to obtain a framework for creating didactic situations that reduce the gap between figure and concept. The results of this study show that the figural (pictoral) structure of an angle (and cube) dominates in the geometric reasoning of the pre-service primary school teachers over its formal conceptual constraints. There were some differences in situations when an image is helpful in solving tasks involving the concepts of the net of the cube and the cube itself.

Even though the Enterprise Resource Planning (ERP) technologies have been significantly addressed in managerial literature, few studies investigated the effects of digital literacy. This study aims to explore the relationship between digital literacy and ERP technology adoption in Bosnia and Herzegovina (BiH), as well as the mediating effects of business innovativeness within that relationship. A valid and reliable structured survey has been prepared and delivered to companies in BiH which use ERP technologies. Based on the recent literature, first order structural equation model has been proposed and tested. The empirical data was based on 82 questionnaire responses from companies in BiH which use ERP technologies. Once the data has been collected, factory data analysis has been performed to purify scales through items' loadings and Cronbach's Alpha values. The resultant scales have been tested for convergent validity through partial least-square path modelling using Smart PLS 3 software. The results indicated that effects of digital literacy on actual system use are significant and positive, and that business innovativeness partially mediates the relationship.
